The Liofilchem® MIC Test Strips is a quantitative assay for determining the Minimum Inhibitory Concentration (MIC) of antimicrobial agents against microorganisms to indicate appropriate patient treatment and for identifying resistance patterns.

Liofilchem® MIC Test Strips are made of special high quality paper impregnated with a predefined concentration gradient of antibiotic, across 15 two-fold dilutions like those of a conventional MIC method.

On one side of the strip a MIC scale in µg/mL is displayed and a code that identifies the antimicrobial agent. Liofilchem® MIC Test Strips are available in a large variety of antibiotic configurations. Each configuration is available in blister packs of 10 strips, 30 strips and 100 strips.

METHOD PRINCIPLE

When the Liofilchem® MIC Test Strip is applied onto an inoculated agar surface, the preformed exponential gradient of antimicrobial agent is transferred into the agar matrix. After 18 hours incubation or longer, a symmetrical inhibition ellipse centered along the strip is formed. The MIC is read directly from the scale in terms of µg/mL, at the point where the edge of the inhibition ellipse intersects with the MIC Test Strip.
